System booted kernel 3.2.0-64, 2. HighPoint RocketU 1144C controller was installed, 3. Areca ARC-5040 was connected to that controller. An error loop during boot contains the following messages: [ 34.084469] usb 8-1: reset SuperSpeed USB device number 2 using xhci_hcd [ 34.101825] xhci_hcd 0000:05:00.0: xHCI xhci_drop_endpoint called with disabled ep ffff88042102e000 [ 34.101918] xhci_hcd 0000:05:00.0: xHCI xhci_drop_endpoint called with disabled ep ffff88042102e040 This continues for about 18 minutes, after which the filesystem on the Areca drive is mounted, and boot process continues successfully, as if nothing had happened. Afterwards the affected drive works seemingly fine, although I experienced some system instability, causing a total system freeze. At this point I am not sure if this instability is related to the problem at hand. I've attached a file generated by apport-cli -f -p linux --save filename.apport . The problem did not appear if I booted an older kernel (e.g. 3.2.0-63), or if Areca enclosure was not attached, or if it was attached using another interface (USB2 or eSATA). The problem was also absent if I replaced the Areca enclosure with another USB3 device (a flash drive). The test machine's motherboard did not have a built-in USB3 controller, but I performed an additional test on yet another computer, equipped with a NEC USB3 controller. That test was done with kernel 3.2.0-64 and the Areca enclosure, and did not replicate the problem. Thus I assume that it is the combination of the RocketU controller and a specific USB3 device that triggers kernel regression. Similar effects happen if Areca enclosure is hot-plugged to the working system. In such a case OS boots fine (as the enclosure is absent during boot). After plugging the Areca, the drive is unavailable for 18 minutes, during which time numerous errors as above are logged. After 18 minutes elapse, drive is mounted and behaves normally.
